FC Gate Valve
Vatac FC Gate Valve combines a forged body and the proven slab-gate and floating seat design used throughout the industry. The slab-gate design provides a metal-to-metal seal on the flow stream and the bolted bonnet provides for ease of maintenance and repair. The Vatac FC Gate Valve has earned a reputation in all types of applications. Available in standard double flange, threaded-end and special block body configurations.  

Features and Benefits

» Positive metal-to-metal sealing (gate-to-seat and seat-to-body)
» Simple, reliable gate and seat design promotes ease of field service and minimal spare parts inventory
» Spring-loaded, pressure energized, non-elastomeric seal between each seat and body assists in low pressure sealing. 

All these advantage ensures Vatac’s new FC Gate Valve Generation: FCS Gate Valves & FLS Gate Valve



Expanding Gate Valves
The Vatac expanding gate valves are designed for oil and natural gas wellhead or other critical service applications with operating pressures from 2,000 psi to 5,000 psi. All Vatac expanding gate valves are API 6A Latest Edition monogrammed equipment and are available in bore sizes ranging from 2-1/16" through 7-1/16".
